5.2. Heat exchanger
To access the exchanger, we have to remove the lining's top cover and the cover of the exchanger. Once we
have gained access from the top, we can remove the turbulator in two different ways. Before carrying out
the removal, please see section 10 TECHNICAL CHARACTERISTICS and check how much these elements
weigh.
5.2.1. Method 1.
Unscrew the cylinder positioner and remove the whole set.
Then, do the same with the helical coupler positioner.

Exchanger top lining.

Heat exchanger cover

Set of positioner + exchanger cylinders.

Set of positioner + exchanger helical couplers.
5.2.2. Method 2.
Tie a cable, wire or cord (length >800mm) to each cylinder. Rise the cylinder until it breaks free from the
positioner, turn it 90° and (with the help of the element we have used to hold it in place) lower the cylinder
as far as it will go. Repeat this process with each cylinder (14 units). Unscrew and remove the positioner,
bearing in mind that the cable, wire or cord attached to it must remain accessible. Remove the 14 cylinders
one by one and do the same with the helical couplers and its positioner.
